Idaho National Laboratory (INL) and Argonne National Laboratory (ANL) seek information from organizations that can provide long-duration energy storage battery systems for benchmark performance testing at their facilities, with selected respondents potentially invited to an RFP process. Acceptable technologies are non-lithium rechargeable electrochemical systems, offered as two 100–150 kWh modules rated for 10–15 kW over 10 hours (max 7x7x7 ft) and one 1000–1500 kWh full-size system rated for 100–150 kW over 10 hours, operating 0–50°C with limited performance/aging loss, providing AC/DC interfaces, arriving pre-built, and having a disclosed =15-year lifetime; lithium-ion, lithium metal, lead-acid, redox flow, non-rechargeable/non-electrochemical, on-site fabrication, and <15-year systems are unacceptable. The scope requires NFPA 855, UL 9540/9540A, NEC/IEEE compliance, hazard assessments, safety systems, SCADA protocols, performance/degradation data, 70%/90%/final design packages, FAT/SAT, manuals, and O&M support. Non-submission timelines include module delivery to INL within about 3 months of final design acceptance, full-scale delivery to ANL within about 6 months, O&M manuals at least 1 month before delivery, and SAT completion preferred within 1 month of installation. Responses should cover technology, physical characteristics, interfaces, safety/compliance, performance, lifetime basis, O&M, schedule, and indicative commercial terms, and data from INL/ANL testing must be publishable.

Idaho National Laboratory and Argonne National Laboratory are seeking information from organizations capable of providing long-duration energy storage (LDES) battery systems for benchmark performance testing at their facilities. Acceptable systems include rechargeable electrochemical batteries in module-scale (100–150 kWh, 10–15 kW over ten hours) and full-scale (1000–1500 kWh, 100–150 kW over ten hours) configurations, with a 15-year lifetime and data publication allowed. Unacceptable technologies include lithium-ion, lead-acid, redox flow, and non-rechargeable systems. Delivery timelines are approximately 3 months after final design acceptance for modules to INL and approximately 6 months for the full-scale system to ANL, with commissioning and site acceptance testing to follow. No budget amounts are specified in this description.
